JACOB I-I. DONNER, OF AURORA, NEBRASKA.

LISTED-CORN CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 487,612, dated December 6, 1892.

Application iiled September 5, 1892. Serial No. 445,076. (No model.)

To all whom t may concern.-

Be it known that I, JACOB H. DONNER, a citizen of the United States, residing at Aurora, in the county of Hamilton and State of Nebraska, have invented a new and useful Listed-Corn Oultivator,of which the following is a specification.

My invention relates to improvements in listed-corn cultivators; and its objects and advantages are to produce a cultivator that may be'einployed for cultivating thoroughly listed corn during the stages of its growth requiring such cultivation, and which by its peculiar arrangement and construction is adapted to etfectually destroy all Weeds and other growth at the sides of the corn.

Various other objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the claims.

Referring= to the drawings, Figure 1 is a perspective view of a listed-corn cultivator constructed in accordance with myinvention. Fig. 2 is a vertical longitudinal sectional view thereof. Fig. 3 is a front View. Fig. 4 is a rear elevation..

Like numerals of reference indicate corresponding parts in all the figures of the drawings.

In practicing my invention, I employ apair of opposite runners 1, whose front corners are cut away or curved in the usual manner and provided with suitable metal facings to prevent wear. These runners have projecting from their opposite sides at their front ends standards 2, and the runners and standards are connected at suitable intervals with crossbars for maintaining them in proper relative position. A draft-bar 3 is located at the front ends of the runners, and to these the hitching devices are to be attached. In rear of the standards 2 the runners are connected from thence to their rear ends by a convexed or curved hood 4, and in plowing extremely young corn I prefer to extend this hood by means of a supplemental hood 5 (shown in Fig. l) and bolted detachably at 6 to the runners. A pair of brackets 7 rise from the runners 2 and are provided at their front ends with transversely-opposite bearings 8, which receive and rotatably support a transversely=` disposed rock-shaft 9, whose ends project beyond the bearings 8. Upon the extremities of the rock-shaft are mounted castings 10, which are provided at their front ends with eyes 11, designed to loosely slide upon the rockshaft and to be adjusted at desired points thereon. Set-bolts 12 pass through the eyes of the casting andimpinge upon the rock-shaft, whereby said castings may be secured at any point of their adjustment.

To the shanks of the castings, at opposite sides of the machine, is bolted a pair of main beams 13, which extend rearwardly and have their extremities downwardly curved to form cultivator-standards 14, which at their eX- trcmities are cylindrical. About midway the beams 13 there is welded to each a supplemental divergin-g beam 15, whose extremity is also downwardly beiititowforrnassupphemental cultivator -standard 16. upon each of the standards 14 and 16 is a bell-cranked or elbow-shaped casting 17, and the same may be adjusted at any desired angle with relation to the beams 13 and 15 by means of set-bolts 18, passed through the eyes of the castings and impinging upon the standards. The outer branch of each casting 17 Ais provided with a reduced bearing 19, preferably formed separate from the casting and removable therefrom, the same being held in position by a set-bolt 20. Upon these reduced bearing portions cultivator-disks 21, having elongated hubs 22, are mounted and adapted to freely rotate. This completes the construction of the cultivator with the exception of a seat-supporting standard 23, which vis of U shape and is mounted upon the beams 13. Bolts 24 pass through the lower extremities of the seat-standards and may be adjusted in any one of a series of bolt-holes 25, with which the beams '13 are provided, so that more or less weight of the driver occupying the seat 26 may be thrown upon the cultivators.

The operation of the invention will be readily understood, but may be briey stated as follows: In plowing extremely young corn the supplemental hood or fender is employed. When the corn is not so young, the hood is removed. The runners straddle the row and rest in the furrows between the ridges and corn and the cultivator is dragged along, so that the disks or cultivators operate upon the sides of the ridges and destroy the vegetation Swiveled` IOS) or undesirable growth therein. It will be obvious that the disks may be adjusted to suit the tastes of the operator, and thus be made to run more or less at an angle to the direction of travel of the plow. By reason of the elbow-shaped casting it will be seen that they may be swung to the rear for throwing the desired amount ot dirt toward the plants, and yet will more nearly maintain their position at substantially right angles with the runners or line of movement of the machine.

Having described my invention, what I claim is l. In a listed-corn cultivator, the combination, with a suitable framework, of a pair of opposite rearwardlyextending beams terminating at their lower ends in standards, el-y bow-shaped castings swiveled on the lower ends of the beams, means for locking the castings upon the standards, and cultivator-V disks rotatably mounted on bearings with which the castings are provided, substantially as specified.

2. In a listed-corn cultivator, the combina? tion, with a framework, of a pair of rearwardly-disposed cultivator-beams terminating in standards, elbow-shaped castings swiveled on the standards and provided at their inner ends with reduced bearings, disks mounted on the bearings, and set-bolts passed through elbow -shaped castings and bearing on the standards, substantially as specified.

3. In a listed-corn cultivator, the combination, with a framework, of a pair of rearwardly-extending beams terminating at their rear ends in depending standards, supplemental diverging beams secured to the main beams and terminating at their rear ends in depending standards, elbowshaped castings swiveled on the standards, means for locking them, and cultivator-disks mounted rotatably on the castings, substantially as specified.

4. In a listed-corn cultivator, the combina-v tion, with the opposite runners, bearings 1ocated at the front ends of the same, a rockshaft mounted in the bearings, beams extending rearwardly from the rock-shaft at opposite sides of the runners and terminating at their rear ends in depending standards carryingbearings,diverging supplemental beams secured to the main beams and terminating at their rear ends in standards carrying bearings, and cultivator-disks mounted on the bearings, substantially as specified.

5. In a listed-corn cultivator, the combination, with the opposite runners, the standards rising therefrom Vand provided with bearings, the transverse rock-shaft mounted in the bearings, the castings mounted on the rockshaft, and the setbolts passing through the castings and impinging upon the rock-shaft, ot' a pair of main beams bolted to the castings and terminating at their rear ends in standards, cultivators mounted on the standards, and the U-shaped seat-supporting standard mounted on the beams, and means for adjusting the seat-supporting standard upon the beams, substantially as specified.

6. In a listed-corn cultivator, the combination, with the opposite runners, standards rising therefrom, a hood connecting the runners, brackets rising from the standards and provided with bearings, a transverse rock-shaft projecting beyond the standards, castings adjustably mounted upon the rock-shaft, beams secured to the castings, supplemental beams secured to the main beams, elboW-shapedcastings swiveled on the standards of the beams, means for adj ustiug the same, and cultivatordisks rotatably mounted on thecastings,sub stantially as specified.

In testimony that I claim the foregoing as my own I have hereto attixed my signature in the presence of two witnesses.

JACOB H. DONNER.
